DETAILED DESCRIPTION OF THE INVENTION

[0034] Leukotrienes are a class of pro-inflammatory lipid mediators derived from arachidonic acid that have been shown to play important roles in a number of biological processes. Arachidonic acid is converted to leukotriene A₄ (LTA₄) in a two-step process mediated by the enzyme 5 -lipoxygenase (5-LO). LTA₄ is converted either to LTB₄ via LTA₄ hydrolase or to LTC₄ through conjugation with glutathione mediated by LTC₄ synthase. Amide bond cleavage converts LTC₄ to LTD₄ and then subsequently to LTE₄. The initial oxidation step is a process that requires the intimate involvement of both 5 -LO and the membrane bound 5-lipoxygenase-activating protein (FLAP). Inhibition of FLAP results in the inhibition of all leukotriene production. LTB₄ is the ligand for the G protein-coupled receptors (GPCRs) BLTi and BLT₂ and both receptors are involved in chemotaxis and cell stimulation in the inflammatory response. [0035] Leukotrienes are lipid mediators of inflammation that are involved in the pathogenesis of ophthalmic diseases, disorders or conditions. Leukotrienes are produced mainly by mast cells, eosinophils, monocytes/macrophages, and neutrophils in response to allergic or inflammatory stimuli. In one aspect, biological tissues in areas that are affected by an ophthalmic disease, disorder or condition have high levels of leukotrienes. The role of FLAP in the leukotriene synthesis pathway is significant because FLAP in concert with 5- lipoxygenase performs the first step in the pathway for the synthesis of leukotrienes. Inhibiting FLAP provides a target for the treatment of leukotriene-dependent or leukotriene mediated ophthalmic diseases, disorders or conditions, including, by way of example, age- related macular degeneration, allergic conjunctivitis, anterior segment scarring, blepharitis, blepharoconjunctivitis, a bullous disorder, cicatricial pemphigoid, conjunctival melanoma, conjunctivitis, contact lens-associated giant papillary conjunctivitis, diabetic retinopathy, dry eye, episcleritis, glaucoma, gliosis, granuloma annulare, Graves' ophthalmopathy, intraocular melanoma, keratitis, keratoconjunctivitis, pain, pinguecula, post-surgical pain, proliferative vitreoretinopathy, pterygia, scarring, scleritis, Sjogren's syndrome, uveitis, vernal keratoconjunctivitis or combinations thereof.

[0036] In one aspect, leukotrienes are involved in the pathogenesis of ophthalmic diseases, disorders or conditions. Ophthalmic diseases, disorders or conditions are treated or prevented by ophthalmic administration of a pharmaceutical composition that includes a FLAP inhibitor compound.

[0037] Disclosed herein is the use of FLAP inhibitors in the manufacture of medicaments suitable for topical administration to an eye of a mammal for the treatment or prevention of leukotriene-dependent or leukotriene mediated ophthalmic diseases, disorders or conditions.

Examples Example 1: Formulation of a FLAP inhibitor

[00156] In one aspect, aqueous ophthalmic solutions that include a FLAP inhibitor compounds were prepared by dissolving a FLAP inhibitor compound in 10% beta- hydroxypropyl cyclodextrin (BHPC) in water. Using this formulation, the following compounds were soluble at 1 mg/mL: Compound A (Na salt), Compound B (Na salt), Compound C (Na salt), Compound I (Na salt), Compound J (Na salt), Compound G (Na salt). Compound F (Na salt) formed a cloudy solution at 1 mg/mL. Example 2: Solution of Compound A

[00157] A solution of Compound A suitable for administration to the eye is formulated with the following components:

Example 3: Solution of Compound B

[00158] A solution of Compound B suitable for administration to the eye is formulated with the following components:

Example 4: Solution of Compound C

[00159] A solution of Compound C suitable for administration to the eye is formulated with the following components:

Example 5: Clinical Trial Evaluating Effect of Topical Administration of a FLAP Inhibitor Compound to the Eye in Reducing Signs and Symptoms of Allergic Conjunctivitis

[00160] A single-center, double-blind, randomized, two way cross-over, placebo- controlled study to evaluate the safety and efficacy of topical administration of a FLAP inhibitor compound to the eye of individuals with allergic conjunctivitis (AC) following conjunctival allergen challenge (CAC). Each subject will receive the active treatment (e.g., a topical formulation of a FLAP inhibitor compound administered to the eye) or placebo. [00161] Ten subjects aged 18-65 years of either gender are to participate in the study. All subjects should have a medical history of ocular allergies (allergic conjunctivitis or rhinoconjunctivitis). Their allergic status should have been confirmed by (1) positive skin prick test to a seasonal or perennial allergen, (2) a positive ocular allergen challenge to the same allergen. [00162] No subject should have glaucoma, anterior or posterior uveitis, clinically significant blepharitis, follicular conjunctivitis, iritis or dry eye; diabetic retinopathy, or progressive retinal disease; presence of an active ocular infection; a positive history of an ocular herpetic infection. Also excluded are subjects that have had previous treatment (within 2 weeks prior to randomization) with any systemically administered or ophthalmically administered corticosteroids; or any systemically administered or ophthalmically administered mast cell stabilizers; subjects who had an upper respiratory tract infection 4 weeks before randomization, or subjects who have undergone ocular surgery within 6 months or had a history of retinal detachment. Female subjects of child bearing potential must have a documented negative urine pregnancy test and must be practicing a medically proven form of contraception during the course of the study period. Written informed consent is obtained from each subject. Conjunctival Allergen Challenge (CAC) Protocol

[00163] Demographic, medical and medication histories are obtained from patients. Patients that are eligible will have CAC performed bilaterally with an allergen to which the patient had previously reacted positively following a skin test. Allergen is instilled at increasing concentrations at 10-minute intervals until a positive reaction is observed.

Patients and physician will then assess signs and symptoms of ocular inflammation: ocular itching, tearing, and redness/burning sensation using a 5 point scale (0 = none to 4= incapacitating) for each symptom at 3, 7 and 20 minutes and 12 hours post CAC. The patient symptom score is the sum of individual scores as rated by the patient. The concentration of allergen inducing a 30% change in the patient symptom score (PD 30), as measured by the AUC symptom score 0 to 20 minutes, will be established. Each patient will then receive the allergen challenge with PD 30 concentration at day 1 of the first period of the cross over and again at day 1 of the second period of the cross over. Each patient will receive the treatment (active or placebo) immediately after allergen challenge. The two periods of the cross over will be separated by a seven-day wash out period.

[00164] The primary endpoint of the study is the variation of patient symptom score (AUC symptom score 0 to 20 minutes) treated versus placebo. Secondary endpoints include the individual ocular signs and symptoms as assessed by the patient and the physician, the overall assessment of the patient, the overall assessment of the physician, safety and tolerability, nasal symptoms, and biomarkers in the lachrymal secretions. Example 6: Rat Model of Allergic Conjunctivitis

[00165] A rat model of allergic conjunctivitis is used to test the effect of topical administration of a FLAP inhibitor compound to the eye on the development of allergic conjunctivitis. Male wistar rats (250 - 350 g) are sensitized by injection with 0.6 mL saline containing ovalbumin (OVA, 1 mg), alum (2mg) and 10¹⁰ killed B. pertussis cells into all four footpads on day 1. Five days later they are boosted by subcutaneous injection with 1 ml of saline containing OVA (0.5 mg) in 10 sites on the back. Local sensitization is performed daily from days 14 to day 42 by instilling OVA in saline (10 mg/ml, 5μl) into the bilateral eyes using a micropipette. Rats are treated with systemic or ocular FLAP inhibitor on days 14 to 42 (as appropriate). The frequency of eye scratching behavior is counted for 20 min post OVA on selected days. Twenty-four hours following OVA challenge on days 14, 21, 28, 35 and 42 rats are anesthetized and the conjunctiva removed and fixed with 10% neutral buffered formalin. 4-μm thick frontal sections are stained and eosinophils counted. The inhibition of eye scratching behavior and conjunctiva eosinophils following topical treatment with a FLAP inhibitor compound to the eye(s) is recorded and plotted using Graphpad Prizm.

Example 7: Mouse Model of RSV-Infected Eye [00166] A mouse model of respiratory syncytial virus (RSV) eye infection is used to test the effects of ocular application of a FLAP inhibitor compound on RS V-induced ocular immunopathology (Bitko V, et al, J. Virol. 2007;81(2):783-90; Bitko V, et al, Nat. Med. 2005;l l(l):50-5). Each mouse eye is topically treated with 60 ng of FLAP inhibitor compound or vehicle (sterile saline) in a volume of 2 μl. The FLAP inhibitor compound is instilled 40 min after virus inoculum and then once daily over the entire duration of the protocol (14 days).

[00167] Instillation of virus and inhibitor in the eye. Female BALB/c mice, 6 to 8 weeks old, were purchased from Charles River Laboratories. RSV (Long strain, serotype A) was grown on HEp-2 cells and purified on sucrose layers to a concentration of 10¹¹ PFU (Bitko et al, Nat. Med. 11 :50-55, 2005). Dilutions were done in phosphate-buffered saline (PBS) immediately before use to a final concentration of 10⁴ PFU/2μL as needed. A similarly diluted sucrose solution was used in sham- infected control mice. Mice were anesthetized by intraperitoneal injection of pentobarbital (50mg/kg), and virus in 2 μL PBS was dropped into the corneal surface and massaged in with closed eyelids. The day of the inoculation was considered day 0. The FLAP inhibitor Compound C was diluted in PBS to 60ng/2 μL just prior to application of 2 μL 40 minutes after the RSV inoculation on day 0 and then each day.

[00168] Duration of the experiment: Eyes will are visually examined daily, and harvested on each of the following days post-RSV inoculation: Day 2, 4, 6, 8, 9, 10, 12, 14 = a total of 8 time points. Three animals are used for each data point i.e. 24 mice treated with a FLAP inhibitor compound C and 24 mice treated with vehicle control (for a total of 48 mice used in the study).

[00169] Ocular pathology. Ocular disease was evaluated with a slit lamp biomicroscope as described previously (Bitko V, et al., J. Virol. 2007;81(2):783-90)15; Girgis et al., Invest. Ophthal. Vis. Sci. 44:1591-1597, 2003). Pathology was scored on a scale of 0 to 5 as follows: 0 = clear eye; 1 = slight redness in the corners; 2 = moderate redness and injection; 3 = conjunctival and corneal injection with ciliary flush; 4 = extensive injection, generally associated with some mucus; 5 = most extensive injection, associated with mucus. Eyes were examined in a coded fashion with the reader unaware of the treatment given. Figure 2 illustrates the effect of the FLAP inhibitor Compound C on RSV eye pathology. Ocular application of the FLAP inhibitor Compound C reduces the pathology score across all observation days, i.e, days 2 - 14 after RSV challenge. The RSV treated eyes showed gummy residue and mucin build up starting at day 4 and heavy mucus build up by day 8. Infected eyes treated with the FLAP inhibitor Compound C were clear of gummy residue and mucin build up on day 8.

[00170] CysLT measurements Eye tissues were homogenized in 1-3 ml lysis buffer (0.5% Triton-X-100, 15 mM Tris Cl pH 7.4) using a polytron homogenizer. The homogenate was centrifuged at 10,000 xg for 10 min at 4 degrees Celsius and supernatant frozen at -80 degrees Celsius prior to processing for leukotriene extractions. Supernatant samples were thawed and precipitated with final volume 10% ice cold methanol, held on ice for 30 minutes, then centrifuged at 10,000 xg for 15 minutes. Denatured protein pellet discarded and lipid containing supernatant assayed for CysLTs (EIA method), at appropriate dilutions to be on the linear part of the standard curve using the procedure described in the Assay Designs kit with a sensitivity ~30 pg CysLT/mL. Figure 3 illustrates the increase in CysLTs in eye homogenates following ocular application of RSV in mice and the effect of Compound C on the levels of CysLTs following ocular application of RSV in mice. Topical treatment with Compound C reduced the levels of CysLTs in eye homogenates. [00171] Interleukin-4 (IL-4) measurements. Eye extract as described above was used to determine levels of IL-4 in the extracts. Figure 4 illustrates the increase in IL-4 in eye homogenates following ocular application of RSV in mice and the effect of a FLAP inhibitor on the levels of IL-4 following ocular application of RSV in mice. Topical treatment with Compound C reduced the levels of IL-4 in eye homogenates. [00172] RSV RNA and protein: RSV is assayed in the ocular tissue on various days using both Western blot and viable virus assay (plaque forming unit; pfu) as described before. IL- 5 is quantified by RT-PCR. RSV RNA and protein were measured in the eye and lung (Urnowey et al, BMC Microbiol. 6:26, 2006). [00173] Administration of the FLAP inhibitor Compound C decreased the production of the Th2 cell cytokine IL-4 as described above but did not increase the viral load in the eye or the lung. Administration of the FLAP inhibitor compound C did not increase RSV mRNA or protein in the eye or the lung (Figure 5). Compound C reduced RSV in the lung. [00174] Infection of an eye eventually transmits into the lung, causing a standard respiratory infection. In some instances, eye serves as a portal of entry for RSV in to the lung. Thus, it is of interest to monitor the lung infection to determine if the ocular application of the FLAP inhibitor compound has any effect on virus replication and quantity of virus in the lung. The mice lung tissue is harvested, homogenates made and assayed for viral titer and Western blot (Matsuse H, et al. Allergology International 2007; 56: 165-169; Bitko V, et al, J. Virol. 2007;81(2):783-90.

[00175] Statistical Analysis. The pathology scores and ocular CysLT and/or IL-4 concentrations were subject to a two-way ANOVA followed by bonferroni post hoc analysis using GraphPad Prism software (GraphPad Software, San Diego, CA).

Example 8: Combination therapy in a mouse Subchronic Smoke Model [00177] BALB/c mice were divided into groups and acclimatized in cages for 24 hours (day 0). The control group was exposed to air and the test group was exposed to smoke from seven unfiltered cigarettes per day for 8 days (day 1 to day 8). FLAP inhibitor compound (3 -(3 -(tert-butylthio)- 1 -(4-(6-methoxypyridin-3 -yl)benzyl)-5 -((5 -methylpyridin- 2-yl)methoxy)-lH-indol-2-yl)-2,2-dimethylpropanoic acid) (30 mg/kg, b.i.d.), DP₂ receptor antagonist 5-{2-[(N-benzyloxycarbonyl-N-ethyl-amino)-methyl]-4-trifluoromethyl- phenyl}-pyridin-3-yl)-acetic acid (10 mg/kg qd), or a combination of FLAP inhibitor compound (3 -(3 -(tert-butylthio)- 1 -(4-(6-methoxypyridin-3 -yl)benzyl)-5 -((5 -methylpyridin- 2-yl)methoxy)-lH-indol-2-yl)-2,2-dimethylpropanoic acid) (30 mg/kg, b.i.d.) and DP₂ receptor antagonist 5- {2-[(N-benzyloxycarbonyl-N-ethyl-amino)-methyl]-4- trifluoromethyl-phenyl}-pyridin-3-yl)-acetic acid (10 mg/kg qd) are administered starting at day 1 and up to day 13. On day 14, bronchoalveolar lavage fluid (BALF) is tested for influx of cells, cytokines, chemokines (e.g., KC, IL-17, MIP-2, IL-6), mucin, and/or proteins. Lung histology is also examined. Trough plasma concentration is shown in the following table:

[00178] Figure 6 illustrates the effect of FLAP inhibition, DP₂ receptor antagonism and combination of FLAP inhibition and DP₂ receptor antagonism on the number of total cells (Figure 6A), neutrophils (Figure 6B) and lymphocytes (Figure 6C) present in BALF. In Figure 6A, * represents P<0.05 vs. air, one-way ANOVA; in Figure 6B, * is P<0.05 vs. smoke, one-way ANOVA with Tukey's, *** is P<0.001 vs. air, one-way ANOVA with Tukey's, "ns" is P=O.055, one-tailed t-test; and in Figure 6C, * is P<0.05 vs. smoke, one- tailed t-test.

[00179] Figure 7 illustrates the effect of a FLAP inhibitor, a DP₂ receptor antagonist and a combination of a FLAP inhibitor and a DP₂ receptor antagonist on the presence of mucin in BALF. In Figure 7A, * represents P<0.05 vs. smoke, one -tailed t-test. In the subchronic smoking mouse model, the effects of a combination of a FLAP inhibitor compound and a DP₂ receptor antagonist compound on mucin secretion in BALF were additive, i.e., a combination of a FLAP inhibitor compound and a DP₂ receptor antagonist reduced the amount of mucin in BALF more than each compound alone. In one aspect, the effects of topical administration of a FLAP inhibitor compound, either alone or in combination with a DP₂ receptor antagonist, to an eye has the same effects (e.g., mechanistically expected) as observed in the BALF.
